Hundreds of young people join Greta Thunberg in climate protest outside UN

​

Teen climate activist Greta Thunberg was joined by swelling and excited crowds of American teenagers at a protest outside the UN headquarters in New York on Friday, in a further blossoming of the youth environment movement given extra thrust by the Swede’s transatlantic boat crossing.

​

Some US children said they were at their first ever climate demonstration; others said they had been passionate about the environment for a while but had been galvanized to act by Thunberg’s rising profile.
